Check Digit Verification of cas no

The CAS Registry Mumber 1257338-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,3 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1257338-41:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*3)+(3*8)+(2*4)+(1*1)=162
162 % 10 = 2
So 1257338-41-2 is a valid CAS Registry Number.

Foerster resonant energy transfer in orthogonally arranged chromophores

Langhals, Heinz,Esterbauer, Andreas J.,Walter, Andreas,Riedle, Eberhard,Pugliesi, Igor

supporting information; experimental part, p. 16777 - 16782 (2011/02/17)

We investigate the ultrafast resonant energy transfer of a perylene bisimide dyad by pump-probe spectroscopy, chemical variation, and calculations. This dyad undergoes transfer with near-unit quantum efficiency, although the transition dipole moments of t
